IGNITION DEVICE FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Patented June 3, 1919.

Original application filed .1 uly 27, 1910, Serial No. 574,030. Divided and this application filed July 30, 1918.

. Serial No. 247,371.

To all whom it may concern:

Be it known that I, JOHN ALLEN HEANY, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Ignition Devices for Motor-lehicles, of which I declare thcfollowing to be a full, clear, and exact description.

This invention relates particularly to that type of dynamo electric machines, which have gas engine ignition mechanism incorporated in their structure. This application is a division of my co-pending application,Serial No. 203,171, filed November 21, 1917, which, in turn, is a division of my co-pending application, Serial No. 574,030, filed July 27, 1910.

The object of the invention is to embody in a single unit, a. dynamo electric-machine, a distributer, and a timer for internal combustion engines. Another object is to dispose the ignition elements in the dynamo, so that they will be easily. accessible and detachable, and have a direct positive driving relationship with the dynamo armature shaft. Further objects, and objects relatin to economics of manufacture and details; 0 construction, will definitely appear from the detailed description to-follow.

I accomplish the objects of my invention by the devices described in the following specification; my invention is clearly defined and pointed out in the appended claims.

A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawings, forming a part of this specification, in which Figure I is a view showing the dynamo in place on an automobile chassis;

Fig. II is a diagrammatical view illustrating the electrical devices connectedin proper circuit;

Fig. III is a view of the dynamo with the ignition devices shown in section;

Fig. IV is a sectional end view of the machine taken substantially on the line IV-IV of Fig. III;

Fig. V is a. detail sectional view of the automatic switch controlling device.

Similar reference characters refer to simiin parts throughout the several views, and

from a main supply tank 13", with intermediate connection 14*.

The chassis frame is indicated at 15*, and bears the various parts of the mechanism making up an ordinary chassis frame, the several p" ts of which need no detail descripticn.

In the diagrammatic view illustrated in Fig. II, the engine cylinders 7, 8, 9, 10, are

illustrated as provided with spark plugs 11 to 14, inclusive, which plugs, of course, have one of their terminals grounded in the en gine and frame while the other is connected .with the respective circuit wires 15 to 18,

inclusive. These line-wires terminate in the relatively stationary contacts of the disgributer, D, the movable contact 19, thereof in whic through the secondary coil 12, the primary coil Z), of the'sp'ark coil B, is connected with the make and break device E,

through its stationary contact 6. The movable contact 21, actuated by a cam or suitable device'22, is connected through a line wire-=23, with the switch contact 24. The

opposite side of the circuit 26, Which runs. I

from the primary coil 7), is connected with a switch contact 27.

connected with a circuit wire 2O,

There are also two switch contacts 28, 29, I

which respectively connect with the circuit line wires 30, 31, that connect with the dynamo electric machine A.

This dynamo electric machine A, is, of

course, provided with an armature, a, and

with a series. field winding G, and a shunt -field winding F, which, through the circuit 30, 31, connect. the dynamo electric machine with a storage battery K, through the switch L, which, as indicated herein, is formed as a unit with the switch member Z, that controls the lines 23, 26, of theigni tion circuit that is nected with the line circuit 30*, 31?.

also connected with the storage battery K, and are main line wires of the dynamo electric machine when the switch L, 1, is' closed. i

A lamp circuit-32, 33, is indicated as controlled 'by a switch M, which switch is con- Of course, it is understood that the various controlling switches of the main line circu t may bevaried to Sll'lh any particular condition. alt is preferred, however, that the switches L, Z, are so arranged and interlocked that the'main line circuit 30, 31, of the generator will be closed in relation to the storage battery K, and main line 30 31, only when'ythe ignition circuit 23, 26, is closed Otherwise, it is apparent that with the enginejat'rest, the storage battery K, might discharge through the dynamo electric machine. J

As illustrating the dynamo electric machine-more in detail, reference is madeto Figs. 3, 4 and 5, wherein the armature shaft 50, is illustrated as suitably. mounted upon anti-friction bearingsg51,and attached to 'a gear 52, which gear 'i's' n mesh with agear 53, mounted upon anti-friction bearings 54, and providing a means for rotating'a make and breakcam 55. I r

The armature 56 is provided with suitable commutator and brush connections arranged in the head-piece 57; These parts are not shown "in detail nor are the fields arranged withinthe casing 58, specifically shown in detail.

, 59, which rovides a suitable bearing1 for the support 0" the gear 52, and an axia y movable sleeve '60.r Thissleeve, as illustrated herein, is, through a spline 61, connected connected through'the gears 2, 3, 4, with in any desired manner.

with a sectional shaft 62, which, in turn, is

the 9 main shaft of the engine.

.The gear 52 has an extended sleeveifii, provid d with helical slots or cam greoves 64, within which are arranged pins 65,that are secured to the axially movable sleeve 60. The sleeve is also provided with a grooved actuator- 66, which, through any suitable le' ver 67, may be utilizedlto actuate a switch device such asYillustrated in diagram at L. l, or for any purpose for controlling the various circuits.

'In Figs. III and IV','I have illustrated the particular form of timing mechanism 'em''? ployed. A T S The gear 53 heretofore refiei red to and the timing cam 55, are inountedftofrotate upon.

Secured in an insulating plate 7 8 is a stud 79 upon which is mounted a trip finger 80, held in normal position by a spring 81, and having a lip 82 and a lever-arm 83. The latter comes in ontact and is moved by the bosses 84 of the timing cam 55, so that the vibrating spring 85' will be drawn away from the contact point 86 at given periods to break the circuit. The vibrator spring 85 is mountedin a block 87, in any suitable man- Withthis arrangement of parts, it is apparent thatthetiming device will1always operate synchronously with the generating apparatus and both devices are conveniently dinary controlling devices, may be mounted upon the engine in lieu of an ordinary ma neto.

The opposite coalesced to form a unit which, with the orv Fig. II there is illustrated I gine, this ignitionswitch may be opened and the'reupo'nthe engine, through its reduced speed, will permit battery K to drive the dynamo electric 'machine A as a motor and cause the automatic switch lever 67, to be moved through the sleeve 60 to properly cut out the ignition and generator circuits at switches L, Z, as hereinbefore described.

Obviously, the elements might be arranged in various forms of juxtaposition or the details of the mechanism might be varied withoutdepa rting from the spirit or intent of the invention, Which,--in the main, contemon drieside of the electric machine, and driving means between the. distributor and theeleetricfmachinearid on theisame side of the electric "machine as the distributor and tlmin'gmechamsm.
